Claims (4)

  1. Automatischer Strang-, Riemen- oder Kettenspanner, der eine Spannrolle (4) zwischen einem Antrieb der Riemenscheibe (7, 8) und einer angetriebenen Riemenscheibe (7, 8) verschiebt, wobei der Spanner einen Schlitten (2) aufweist, an dem die Spannrolle (4) befestigt ist und der sich entlang einer ersten Führungsbahn (3) verschiebt, die an einem Gehäuse angebracht ist, und eine Komponente, durch das der Schlitten (2) mit der Spannrolle (4) verschoben wird, dadurch gekennzeichnet, dass
    - der Schlitten (2) an seinem unteren Teil eine zweite Führungsbahn (2a) mit einer Vertiefung (2b) aufweist, deren Auflagefläche in Richtung der Verschieberichtung geneigt ist.
    - die Komponente, durch die der Schlitten (2) mit der Spannrolle (4) verschoben wird, eine Passfeder (1) mit gegenseitig geneigten oberen und unteren Arbeitsflächen (10, 11) bildet, wobei ein Winkel zwischen den Arbeitsflächen (10, 11) der Passfeder (1) gleich einem Neigungswinkel der Lagerfläche des Schlittens (2b) ist:
    wobei
    die Passfeder (1) mit der ersten Führungsbahn (3) und der zweiten Führungsbahn (2a) derart zusammenwirkt, dass die obere Fläche (10) der Passfeder (1) auf einer unteren Fläche der ersten Führungsbahn (3) aufliegt, während die untere Fläche (11) der Passfeder (1) die Lagerfläche der Vertiefung (2b) berührt; und
    - unter einer konstanten Kraft (F), die auf die Passfeder (1) ausgeübt wird, beispielsweise durch eine Feder, die Passfeder (1) so angepasst ist, dass sie sich entlang einer Richtung der Kraft (F) verschiebt und der Schlitten (2) mit der Spannrolle (4) so angepasst ist, dass er sich nach unten verschiebt.
  2. Der Spanner nach Anspruch 1, dadurch gekennzeichnet, dass der Winkel zwischen den Arbeitsflächen (10) und (11) der Passfeder (1) zwischen 3 und 20 Grad liegt.
  3. Der Spanner nach Anspruch 1, dadurch gekennzeichnet, dass die Passfeder (1) an ihrem breiteren Ende mit einem Vorsprung (9) versehen ist, der mit dem Rand der ersten Führungsbahn (3) zusammenwirkt und die Verschiebung der Passfeder einschränkt.
  4. Der Spanner nach Anspruch 1, dadurch gekennzeichnet, dass die Passfeder (1) ferner an ihrer Seitenfläche mit einer Ratschen-Zahnstange (5) versehen ist, während die erste Führungsbahn (3) mit einer beweglichen Sperrklinke (6) versehen ist, die mit der Ratschen-Zahnstange (5) der Passfeder (1) zusammenwirkt.
